• A. (a) $\to$ (i), (b) $\to$ (iii), (c) $\to$ (ii), (d) $\to$ (iv)
• B. (a) $\to$ (iv), (b) $\to$ (i), (c) $\to$ (ii), (d) $\to$ (iii)

Answer 2

The correct arrangement is: (a) $\to$ (iv), (b) $\to$ (i), (c) $\to$ (ii), (d) $\to$ (iii)
(i) Echinodermata, such as Asterias, exhibit radial symmetry in adults and bilateral symmetry in larvae.
(ii) Scorpions, found in Arthropoda, respire through book lungs.
(iii) Bioluminescence, the emission of light by living organisms, is prominently observed in ctenophores, exemplified by Ctenoplana.
(iv) Locusts are a type of gregarious pest.
